It took me a while when I first downloaded the original Pattern Switcher. So I hope this helps......
Once you create a folder inside your pattern folder, i.e. space_marines, you go into that folder and create another folder like "Halfed". You then put your downloaded skins (wtp files) for the halfed marines into that "Halfed" folder. when you run the switcher you should see the "Halfed" folder and you click import. It should then import the pattern files from the "Halfed" folder into that races tab.
Im still having a hard time with the brand new version of the switcher. I got the folders made and the tabs work and import for Tau and Necrons, but I can't get the patterns to work in the game
Anyone got the new version of the switcher for dark crusade working? As I said, I have the new races for dark crusade in the switcher but cant get the switcher to even recognize dark crusade. I went into configure and adjusted it per the readme files instructions, but no dice. I can see the imported files in the switcher, but cant get them to load into dark crusade. Any suggestions?
